Abstract

Emission inventory plays important roles in the assessment, monitoring, modelling and management of emissions of air pollutants which have devastating impacts on human health, vegetation and climate. The study estimates the quantities of selected air pollutants generated from a metal recycling process involving charging, melting and tapping using standard emission factor approach. The pollutants considered include Nitrogen oxides (NOx), Sulphur oxides (SO2), Carbon monoxide (CO) and Total Suspended Particulate (TSP) matter. The total quantity of material consumption daily represents the activity level. The total quantity of material consumed was combined with appropriate published emission factors by United States Environmental Protection Agency (USEPA). The result showed that the quantities of NOx, SO2, CO, and total suspended particulate (TSP) matter emitted are 0.013, 0.012, 0.110 and 2.323 tonne/day, respectively. The percentage proportion of TSP emitted is 94.5 % followed by CO (4.5 %) while the quantities of NOx (0.5 %) and SO2 (0.5 %) are similar. The inventory information in this study is expected to serve as a guide to researchers and policy makers to know the fate and effects of air pollutants in the study area for adequate air quality management.
